NOTE: Hotrolling and coldrolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hotrolled or coldrolled. HOTROLLED STEEL. Hotrolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

A rolling mill which uses the "hot rolling" method is capable of processing more gross weight of metal than any other manufacturing process. Rolling mills which use the "cold rolling" method can process the most tonnage from the entire range of cold working processes.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Hot Rolled Sheet Steel Hot Rolled Sheet Steel is an unprocessed, mill edge coiled product and does not include any processing such as temper rolling, tension leveling, pickling, oiling or side trimming. Hot Rolled products are produced to ASTM Specifications A1011, A659, A635 or .
Sep 11, 2014· Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by annealing and/or tempers rolling.
